  1. A good link on hydrogen storage densities

     

    http://www.aip.org/tip/INPHFA/vol-10/iss-1/p20.html

     

    Says hydride systems can actually store more hydrogen in a smaller space than liquid hydrogen. But the weight of the storage tank is a major issue. It also looks like many of these systems have huge issues in how they will be recharged. It is not as simple as hooking up a hydrogen hose to your vehicle.

     

    Looks like an effecitve storage method continues to be one of the unsolved engineering problems facing hydrogen vehicles.

     

    Actually here is another link to a government agency that seems to have a lot of good info about renewable energy.

  2. check this relay, maybe it's stuck in the on position. Maybe you can set it on some kind of timer to go off after 9 minutes of driving?

     

    Man, I owe you big. My POS Chilton manual didn't show an A/F relay or fuse. The manual made it look like the thing was powered directly off the ECU. Thought maybe your diagram was for a different car. But I poked around anyway and found the blown 25 amp fuse.

     

    $2.82 for 5 fuses and the light is out. Let's see if this holds up. Sure beats $500+

     

    Thanks. After what I went through last year I overlooked the obvious.

     

    BTW, those heaters draw some amps. The Chilton manual listed the resistance as 1.2 ohm at 68° and 3.4 ohms at 1472°. Thats 10 amps-120 watts per heater. Those suckers get hot!

  3. Anybody have any ideas on what would make a car burn out the O2 sensor heaters?

     

    Last year my wife's 2001 Toyota Sienna had the heating elements go out on both primary O2 sensors. They went out 1 at a time within 2 weeks of each other. Two weeks after that I got the smog check notice, so had to fix them. Today, only 12,000 miles later, the computer threw error codes for BOTH heaters at the same time.

     

    This van has the wide band types. At $250 EACH from Toyota ($300 each for the Bosch units at Autozone) I do not want to replace them until I know what is going on.

     

    What the F could cause both heaters to go out at the same time? All I have is the codes right now, but the ones I took out last year are open circuits when checked with an ohm meter.

     

    The van seems to run fine. Any chance I could splice a 1.2 ohm resistor in place of the heaters and not have the engine run bad?

  4. I was going to say, full auto license are not that hard to get. Just expensive. Some states make things more difficult than others too.

     

    Back in the early 80's a buddy was a gun dealer and wanted to sell me a completely legal, full auto Uzi with silencer. I couldn't afford the $800 (including permits). These days I could easily sell that for 10 or 20 times what it would have cost back then. A lot of people think full auto weapons are an excellent investment. Most definitely outperform the stock market.

  5. In October' date=' 1986 I was at the Federal Law Enforcement Academy in Brunswick, Ga and the guys from Glock came over from Smyrna and gave us a day long demo on their product line... I've never carried anything but a Glock Since... It's one fo the most durable and concealable weapons made and the accuracy is top shelf.

    Definitely one of the most innovative guns of our time. Being a fan of Smith and Wesson revolvers, I never liked the trigger feel of the Glock. But if I ever had to carry a pistol, that would be one of the first models I would look into.

  6. Thanks Dale. That looks perfect. A couple of guys on LS1TECH managed to make it work without the right most tensioner, but people questioned whether there was enough belt area contacting the water pump pully and the crank pully to be effective. Your set up definitely covers the water pump. I assume the car is on the road so no problems?

     

    The slickest I have seen so far was this set up

    The guy had to machine a new water pump impeller so he could spin it backwards.

     

    Here is the link. Beyond what I can do.

  7. Anyone know a clean way to mount just an alternator and mechanical water pump on an LSX series motor? Want to get rid of the power steering pump, and wouldn't mind deleting one or more of the idlers in the process.

     

    Have been searching both hear and on LS1TECH.com but can't seem to find what I want. Do the serpentine belts come in different lengths? Anyone know a source for info on belt lengths?

  8. A train that accelerates instantly at each hour would get further than the train that was constantly accelerating.

     

    Other way around. 75 mph for the first hour, 80 mph for the second, etc. With a constant acceleration the speed would gradually increase for the first hour resulting in a shorter trip.

     

    Yeah, two ways it could be done. Set the accel = 5mph/hr then plug and chug, or just add up the distance traveled at a constant speed each hour until you get 3000 miles. Don't make it any more complicated than that.

  9. I have seen cars where the PCV valve got clogged with oil and they most definitely did blow oil out the dipstick tube. The car had a few miles on it, so might only happen with an older engine.

     

    There is really no reason not to use a PCV valve. Better to have a slight vaccum in the crankcase then a positive overpressure from ring blowby. The vaccum will help seal the rings.

  10. Sounds exactly like what Pete Paraska went through with his Z. In his case, it was the gas tank liner coming loose and blocking the fuel inlet.

     

    If you have a piece of debris floating around your tank, it will run until the piece gets sucked up onto the inlet. Turning the pump off lets the debris float away, then gives you some good run time before it eventualy finds its way back to the inlet and blocks the fuel flow again. A blocked fuel line would also make the pump noisey.

  11. That is just a regular oxy-acetelyne torch, albeit a supposedly very high quality one. I have been on metalworking sites that talk about how the Henrob is the only torch to buy for precision work.

     

    As far as gas welding aluminum, watch some of Jessie James TV specials. He gas welds aluminum tanks all the time.

     

    A good link on why to buy a torch. Also mentions the Henrob set up.

    Actually the whole web site in the link above is excellent.
